Comment (by richardpl):
I managed to decode this file (first you need to add 16bit frame type to
each packet and convert bitstream from bigendian to little endian) with
reference decoder EVRC-B.
Reference decoder EVRC-C with its executable with name fourgv did not
correctly decoded file. So this file probably is not EVRC-WB.
I failed to find GUID as used in qcp on internet and fourcc (if) used in
3gpp2 files.
